Question
Hi I have a question, Can you help me to find an example for my reflection for my Biology. This chapter is about An introduction to Metabolism and relate that to the BIB(Big Ideas in Biology)
BIB 1: Evolution Central Paradigm in Biology
Evolution is the fundamental organizing principle in biology - it explains both the unity and diversity of life. All living organisms share a common ancestor. Species evolve over time, and new species can arise when allele frequencies change due to mutation, natural selection, gene flow, or genetic drift. Darwin's theory of evolution by natural selection which includes variation, inheritance, change, and adaptation is supported by evidence from many sub-disciplines within biology and other disciplines of science.
Learning objectives:
Students will be able to explain the process of evolution by natural selection, including molecular mechanisms, and how that process has affected all life forms in the past and continues to do so today.
Students should also be able to explain historical and current examples.
Students should be able to summarize the evidence for evolution and modifications made to the basic Darwinian explanation (genetic drift and gene flow).
BIB 2: Biological Entities Function as Systems
Biological systems, such as molecules, cells, organisms, and ecosystems are made up of multiple components that interact to form complete networks. The consequences of this interaction are that the system possesses properties call "emergent properties" that are not possessed by the components and are unique to the system. Another consequence of this interaction is that if one of the components is changed, that can change the properties of the system.
Learning objectives:
Given a biological system, such as a molecule, cell, or single-celled organism you should be able to explain how the parts of the system interact to produce the emergent properties of the system.
Apply the scientific process by using models to predict or demonstrate how changes in one component affect the entire system.
BIB 3: Structure and Function of Biological Systems are Interdependent
Biological structures exist at all levels of organization, from molecules to ecosystems. A structure's physical and chemical characteristics influence its interactions with other structures, and therefore its function. Fundamental structural units, and the molecular and cellular processes they participate in, are conserved through evolution and yield the extraordinary diversity of biological systems seen today.
Learning objectives:
Given the different levels within the hierarchy of science in general and biology in particular, students will be able to analyze the interrelationships between structural elements at each level and the functions performed.
Students will also be able to predict the resulting changes that may occur when a structural element of a hierarchy is changed.
BIB 4: Matter and Energy are Required by Biological Systems
Biological systems are organized and regulated to operate as distinct entities separate, but dependent, on the environment around them. In order to maintain the dynamic steady-state, they must acquire matter and energy and so are subject to the laws of physics and chemistry whcih underlie processes such as metabolic pathways and homeostasis.
Learning objectives:
Students will be able to explain the processes by which energy enters living organisms and what happens as it passes between and through all levels of the biological hierarchy.
Students will also be able to compare and contrast the processes by which matter moves through and between organisms/levels of organisms.
BIB 5: Information Processing and Transfer are Essential
All biological systems depend on specific interactions and information transfer between the components of the system and between the different system levels. Information exchange between components of a system form the basis of the successful functioning of that system, whether it be a cell, and organism, or an ecosystem.
Learning objectives:
Students will be able explain how information is stored in biological systems, how it is accurately replicated, and how the information is processed and used by individual cells/organisms.
Students will also be able to explain how genetic and epigenetic information flows between generations and the patterns of inheritance that result.
Students will describe multiple mechanisms that system from cells to organisms have multiple mechanisms to perceive and respond to changing environmental conditions.
Explanation / Answer
If you need an example for each of your BIB, then it follows:
BIB1: Evolution Central Paradigm in Biology
Species evolve from common ancestors. Like the eel and lampreys are evolved from a common ancestor, so are the finches of the Galapagos island. They radiated and gave rise to different species based on their habitat and food habit. Each of the species of finches had a different beak shape, although, they had the same ancestor. The environment lead to mutation and changes in the molecular level which along with genetic drift lead to speciation. If we take into consideration of bats and humans, they both have forearms , however, modified which suits the fuction accordingly. Both bats and humans evolved from the same ancestors. Again, natural plays a huge role in choosing the one which is more fit and has a greater adaptation with the changing environment. A very common example is of the industrial melanism, where before the industrial pollution the light-colored moths were selected but when pollution happened the dark colored moths got favored naturally as they could now camouflage well with the dark trunks of the tree.
BIB 2: Biological Entities Function as Systems
At all the levels, cellular as well molecular, interdependence occurs. The nucleus controls the functioning of other organelles. The proteins required for various functioning are produced in the nucleus, processed in the ER , packaged in the Golgi bodies and transported via cytoplasm to the exterior.
BIB 4: Matter and Energy are Required by Biological Systems
This can be explained with the help of energy flow in a food web and the energy pyramid. The solar energy enters the hiererchy via plants and is transferred to each trophic level. All the metabolic activities of the body requires energy for functining.
BIB5: Information Processing and Transfer are Essential
The behavior of an animal is due to functions encoded in their genes. This information is transferred from one generation to the next. This information often gets modified due to various factors leading to genetic mutations or epigenetics which is an alteration in the expression of a gene without changing the genetic code. The replication of the nformation occurs during DNA replication and this copy is transferred to the offspring through the gamets.
You can choose any of the above, however, an easy one will be the BIB1.
